Product Performance

531X305NTBAJG1 adopts a high-precision 16-bit A/D conversion chip and temperature compensation algorithm, with measurement error ≤0.25% over the full temperature range, ensuring the accuracy and repeatability of process parameter acquisition. The channel-level 2.5kVAC electrical isolation design combined with hardware filtering circuit provides common mode rejection ratio ≥100dB, effectively resisting electromagnetic interference and ground loops in industrial sites.

Supporting hot-swap function, the system remains in normal operation during module replacement, reducing maintenance downtime by more than 90%. Integrated with comprehensive self-diagnosis functions, it can real-time detect channel open circuit, short circuit, overvoltage and module power supply abnormalities, with fault response time ≤10ms, triggering alarms and recording fault codes via the system controller. Seamlessly compatible with Mark VIe control system, data update delay ≤50ms, meeting real-time control requirements, with mean time between failures (MTBF) ≥150,000 hours.
